I should probably clarify. I don't expect anybody to take $500 for that gun, but that's about what I would consider my max if someone offered me a chopped and refinished TL. I bought a couple of blue TL targets last year that had been refinished decades ago, and I paid about twice that much for each them. I consider a decent old refinish to be almost an original finish. A TL with a good refinish is still a TL, and I would consider paying up to $1200-1500 for a refinished TL if the job has been carefully done.
I'm not talking exclusively about old refinishes, either. A modern master refinisher can do a job on a TL that would not drive me away.
